A new approach to horticultural spraying could be the result of a collaboration between design students from Kyoto Institute of Technology and Swinburne University in Melbourne.

“Yanmar is a manufacturer of farm machinery, and they asked us to solve a big problem for grape-growers,” says Natsumi Takamatsu, a design student at Kyoto.

“What we developed was a sprayer to mitigate the drift of sprayed agricultural chemicals. Really it was the actual viticulturists when we interviewed them and they were saying things like ‘If only I had something like this.’”

“Australia and Japan enjoy the seasons at opposite times of the year so we can conduct field research in the vineyards all year,” says Yoshiro Ono from Kyoto Institute of Technology.

Harnessing the sun and improving agriculture

Mitsubishi Heavy Industries have built a pilot concentrated solar power plant in Yokohama. It uses CSIRO technology now being manufactured by South Australian company Heliostat SA.

Professor Thomas Maschmeyer is working to integrate new battery and solar cell technologies into the walls and roofs of new houses, and to transform the somewhat ‘black art’ of catalysis—the process that cracks crude oil into useful fuels, oils and chemicals at every refinery. He has already helped to create over 200 new jobs with four spin-out companies.

Lithium batteries have transformed power storage—from smartphones to electric cars and submarines. But like every battery their chemical composition changes through every charge cycle.

Lithium ions sitting in layers of graphite move between electrodes and change the oxidation state of, magnesium oxide, for example. The chemical rearrangements cause the graphite and oxide layers to physically expand and contract by up to 15 per cent at every cycle, cracking and detaching from the electrodes.

In the future, the entire roof of your house could be a solar panel, and you could harness the power of the sun to charge your mobile phone while on a remote bushwalk, thanks to cheap, printable solar cells.
